The Casio G-Shock GG-B100XMH-5AER is part of the exclusive Master of G line and bears the name "Master in Horizon Gold". Inspired by the golden horizon where earth and sky converge, this watch combines rugged performance with elegant style. The stainless steel bezel is finished with a light yellow gold ion plating, key metal components feature a warm brown ion coating, and the dark brown bio-based resin strap completes the powerful nature-inspired design.
